[0002] Chemical auxiliaries are the main raw materials that play an auxiliary role in chemical reactions and production processes. Chemical auxiliaries can improve the performance of raw materials and increase the reaction efficiency of raw materials. There are many types of chemical auxiliaries, including metal processing auxiliaries, plastic auxiliaries, paper-making auxiliaries, building auxiliaries, and coating auxiliaries. Among them, when producing metal processing auxiliaries, the required raw materials need to be quantitatively added to the production equipment for mixing. Since the raw materials of metal processing auxiliaries include a variety of powder materials, the powder materials are usually stored in bags, and a large amount of dust is generated when the powder materials are put into the production equipment, which will not only cause loss of the powder materials but also pollute the surrounding production environment and reduce the quality of chemical auxiliary production. Summary of the Utility Model

Detailed implementation manners

[0032] To facilitate the understanding of the present utility model, the present application will be described more comprehensively with reference to the relevant attached drawings; the preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0033] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs; the terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0035] As Figures 1 to 5 shown, the present application provides a quantitative feeding device for chemical auxiliary production, including a feeding tank 100 and a discharge pipe 120. The discharge pipe 120 is fixed at the bottom of the feeding tank 100, and a flow control valve 121 for controlling the flow rate of the auxiliary agent is fixed on the discharge pipe 120. The powder is conveyed to the production equipment through the discharge pipe 120, and it further includes a protection component 110;

[0036] The protection component 110 includes a feed bin 111 and a flexible plate 112;

[0037] The feed bin 111 is a hollow cylinder with an open upper end, and it is fixed on the feeding tank 100;

[0038] The flexible plate 112 is an arc-shaped rubber plate, and it is fixed on the feed bin 111. There are four flexible plates 112, and the four flexible plates 112 form an inverted cone with a hollow interior and an open end face;

[0039] There is a gap between adjacent flexible plates 112, and the gap is in the range of 0.1 cm to 0.15 cm. That is to say, the four flexible plates 112 are of a split design;

[0040] A material guiding cylinder 113 is fixed at the bottom of the feed bin 111. The material guiding cylinder 113 is a hollow cylinder with open ends at both ends. The free end of the material guiding cylinder 113 extends into the feeding tank 100 to facilitate the conveyance of the powder material into the feeding tank 100.

[0041] It is easy to understand that when the bag mouth of the bagged powder material is facing the flexible plate 112 and abuts against the flexible plate 112, the four flexible plates 112 will be opened, and the powder material will enter the feed bin 111. At the same time, the powder material bag abuts against the flexible plate 112, covering the opening of the flexible plate 112. At this time, the dust generated by the falling of the powder material will be blocked in the feed bin 111, and it is not easy to generate dust.

[0042] Specifically, as Figures 1 to 5 shown, the diameter of the material guiding cylinder 113 is not greater than the diameter of the feed bin 111, and the difference is in the range of 2 cm to 3 cm. That is to say, after the powder material enters the material guiding cylinder 113, due to the relatively narrow internal space and thin air, it is not easy for the powder material to generate dust.

[0043] In the above embodiment, when the bagged powder material is opened and abuts against the flexible plate 112, with the bag mouth facing the flexible plate 112, the four flexible plates 112 will be opened, and the powder material will enter the feed bin 111. At the same time, the powder material bag abuts against the flexible plate 112, covering the opening of the flexible plate 112. At this time, the dust generated by the falling of the powder material will be blocked in the feed bin 111 and enter the feeding tank 100 along the material guiding cylinder 113, which can reduce the dust of the powder material. After the powder material bag is lifted, the flexible plate 112 will reset due to the loss of pressure, blocking the dust from flying, reducing the material loss, and improving the quality of product processing.

[0044] In some embodiments of the present application, as Figures 1 to 3 shown, it further includes a mixing component 200 for mixing the powder material;

[0045] The mixing component 200 includes a stirring rod 210, a turntable 211, and a material leveling plate 230;

[0046] The stirring rod 210 is movably connected inside the feeding tank 100, and its free end extends into the discharge pipe 120;

[0047] The turntable 211 is rotatably connected to the feeding tank 100. The stirring rod 210 and the turntable 211 are connected by a connecting rod. The turntable 211 is used to drive the stirring rod 210 to rotate, which can avoid the blockage of the discharge pipe 120 and does not affect the conveying of the powder material at the same time;

[0048] The material leveling plate 230 is fixed on the stirring rod 210 near the discharge pipe 120. There are two material leveling plates 230, and the two material leveling plates 230 are mirror-symmetrical.

[0049] It is easy to understand that by rotating the turntable 211, the stirring rod 210 can be driven to rotate, and the powder material is stirred by the material leveling plate 230, so that various powder materials are mixed together, which can improve the production efficiency of chemical additives.

[0050] Specifically, as Figure 2 shown, a scraping plate 231 is fixed on the material leveling plate 230. The scraping plate 231 can be in contact with the inner bottom of the feeding tank 100. The scraping plate 231 can scrape the powder material at the bottom corner of the feeding tank 100 downward, reducing the loss of the powder material.

[0051] Specifically, as Figure 2 to and Figure 3 shown, a material scattering plate 220 is fixed on the stirring rod 210 near the material leveling plate 230;

[0052] There are two material scattering plates 220, and the two material scattering plates 220 are mirror-symmetrical. A plurality of auxiliary plates 221 are fixed on each material scattering plate 220.

[0053] It is easy to understand that by arranging the material scattering plate 220, the contact area with the powder material can be increased, the mixing efficiency of the powder material can be improved, and at the same time, with the cooperation of the auxiliary plates 221, the mixing efficiency is further improved.

[0054] In the above-mentioned embodiment, rotating the turntable 211 can drive the stirring rod 210 to rotate. The powder material is mixed by the material scattering plate 220 and the material leveling plate 230, and the contact area with the powder material is increased by using the auxiliary plates 221 to improve the mixing efficiency. Premixing treatment is carried out for the powder material to enter the production equipment. After the mixing is completed, the flow control valve 121 is opened, so that the mixed powder material enters the production equipment from the discharge pipe 120 at a set flow rate, which is not easy to cause blockage in the production equipment and improves the processing efficiency.

[0055] In some embodiments of the present application, as Figures 1 to 3 shown, two parallel eccentric wheels 212 are fixed on the stirring rod 210 near the guide cylinder 113;

[0056] The eccentric wheel 212 is a cylinder, and its central axis is far from the stirring rod 210. That is to say, the eccentric wheel 212 and the stirring rod 210 form an eccentric structure;

[0057] Two notches 114 are formed in the material guiding cylinder 113. When the stirring rod 210 rotates, one eccentric wheel 212 can extend into one notch 114.

[0058] Specifically, as Figure 2 and Figure 3 shown, an arc-shaped gravity plate 213 is fixed on the side of each eccentric wheel 212 close to the material guiding cylinder 113. The gravity plate 213 is used to increase the weight of the eccentric wheel 212, thereby increasing the hammering force of the eccentric wheel 212;

[0059] A soft bag 214 is fixed on the side of the gravity plate 213, and gravity powder is filled in the soft bag 214 to further increase the hammering force.

[0060] In the above embodiment, as the stirring rod 210 rotates to drive the eccentric wheel 212 to perform eccentric motion, the eccentric wheel 212 can repeatedly hammer the powder falling from the material guiding cylinder 113 during the motion process, which is convenient for hammering the agglomerated powder, avoiding the generation of air bubbles when the agglomerated powder enters the production equipment, and at the same time can hammer out the air between the powders, making the powders loose and not easy to block in the material guiding cylinder 113.

[0061] The above description is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
